the answer is right there in your response you said a white person acting like a nigger or a poorly behaved black person according to your post but a black person acts as a nigger because nigger refers to black people the whole point is to acknowledge that people of any race can be rude and poorly behaved and any name for such a person that refers to a racial slur like nigger is inherently racist why not just use accurate descriptors like rude and poorly behaved for people who you believe act in that way what benefit do you gain from choosing the term nigger over any other more accurate phrasing
